Some time since I posted here. That's probably good news.
I recently lost at high speed the two side covers (left and right) from underneath the engine.
The middle cover only fell off at low speed and I was able to recover it intact.
Probably some previous mechanic forgot to tighten the screws on these covers.
The covers were all made of a black plastic. Anyway, I'd like to replace them and it wouldhelp meto know what the technical description for these covers is and if possible, the Mercedes part numbers. If it helps, the part number for the middle piece which I still have is 140 524 10 30.

Regards

 

www.alldata.com identifies my bottom engine access panels as:
"Engine compartment Panel" or "Bottom engine compartment panel" for below oil pan

"Engine compartment encapsulation panels" or "engine encapsulation panels" for access to engine mounts (same thing I think)

"Bottom Engine Compartment Trim" or "engine compartment panelling" is referenced for removing engine or oil change(still all the same as I know it).

I have long since left mine off, from doing under car repairs, oil changes, etc. No difference in ride, etc. Maybe 0.01% noise increase, but not recognizable from inside the car that I can notice.

 

Thanks for the info, Bill.
Reason I wanted to replace them is to protect what's underneath from dings (e.g. stone chips) and bumps.
As with having a clear filter over my camera lens, it's a heck of a sight cheaper to replace the filter than the lens if the front gets scratched.
Likewise with the car, I'd rather the covers took the strain. I can see they are inconvenient for maintenance.
